Headway 15Ah LiFePO4 Cylindrical Lithium Ion Battery, Used/Tested

These Headway LFP cells are an excellent option in demanding applications such as e-bikes, scooters and even EVs. With an extremely low internal resistance, they're capable of 10C(!) discharge. That's 150 amps, wow!

We test all used cells for capacity, internal resistance and voltage prior to shipping. These will be at nominal voltage (3.2v for LiFePO4, 3.6v for li-ion) and require full charge prior to operation.

 These have tested at greater than 95% capacity at 20a discharge.

 Price is per cell, which includes fasteners, bus bar and plastic bracket.

Lithium Battery Safety

• Misusing or mishandling a lithium-ion battery may cause fire or explosion, which can result in personal INJURY or DEATH and property damage. You MUST read the safety warnings and resources before purchasing, using, and/or handling batteries. Even if properly handled, lithium-ion batteries may still catch fire or explode. The buyer acknowledges these risks and absolves Higher Wire Inc. of any responsibility for any damage these cells may cause.
• Unless otherwise stated, batteries sold by Higher Wire are unprotected and not recommended by us or their original manufacturers for use unless equipped with a protection circuit board (PCB), battery management system (BMS), and/or similar device.
• Lithium batteries must be properly disposed of – NOT in a fire or in the trash. Laws vary at the city, state and national level, and it is the buyer’s responsibility to ensure they are recycling lithium batteries properly. Many local governments and retail stores offer free recycling.
• Unless otherwise stated, batteries sold by Higher Wire are used and have no warranty, either from Higher Wire or the original manufacturer. Although we visually inspect and analyze/grade all batteries prior to sale, it is the buyer’s responsibility to inspect all batteries for physical damage, corrosion, and voltage upon receipt. Contact us immediately if there are any issues with an order, and do not use any battery that is damaged or below 3.0 volts upon receipt.
• Unless otherwise stated, batteries sold by Higher Wire are charged to 40% SOC (~3.4v) per IATA and DOT regulations. Charge battery fully to 4.2V before first use.
• Never attempt to mix and match brands, including models as well as old and new, used, and unused lithium-ion batteries. It is the buyer’s responsibility to ensure a battery is compatible with the intended application. Contact us with any questions, including technical.
• Unless otherwise stated, batteries sold by Higher Wire are shipped as UN3480 per DOT and IATA regulations. We ship using ground shipping to minimize risk of damage to persons or property.
